Problems solved by technology

However, since the peripheral edge of the cylindrical vertical milling cutter has a helical surface structure, general-purpose equipment or instruments are used for measurement, and there are no special process equipment or auxiliary tools to be used with it. The face wear zone height VB and its area are extremely difficult
It is not difficult to find that there is a principle error in the previous direct detection method

Abstract

The invention discloses a cylindrical vertical milling cutter peripheral edge wear evaluation method and device and a storage medium, and the method comprises the steps: reconstructing a three-dimensional rectangular coordinate of a peripheral edge wear area boundary point according to a received image of a milling cutter peripheral edge rear cutter surface wear area; according to the three-dimensional rectangular coordinate of the boundary point of the peripheral edge wear area and a mapping function for mapping the flank surface of the peripheral edge of the milling cutter into a plane alongthe radius by taking the axis of the milling cutter as the center, converting the peripheral edge wear area into a three-dimensional space plane; according to the three-dimensional space plane of theperipheral edge abrasion area, obtaining plane coordinates of abrasion area boundary points of the first rear cutter face and the second rear cutter face; combining the wear areas of the first flanksurface and the second flank surface to obtain a combined wear area image of the peripheral edge flank surface; and analyzing the formed wear region image to obtain the evaluation of the wear of the peripheral edge wear region. By analyzing the reconstructed wear area, the evaluation of the wear of the peripheral edge of the milling cutter is realized.

Description

technical field [0001] The invention relates to the application field of mechanical processing technology, in particular to a method, device and storage medium for evaluating the wear of a peripheral edge of a cylindrical vertical milling cutter. Background technique [0002] In the process of metal cutting, tool wear is an important factor affecting the processing quality, production efficiency and manufacturing cost of parts. In order to detect tool wear in the cutting process, researchers have proposed a variety of wear detection methods, which are mainly divided into two categories, direct detection method and indirect detection method. Direct detection methods usually include contact measurement method and video image measurement method; indirect detection method is to obtain the wear amount of the tool through the change of relevant physical quantities in the processing environment. Obviously, the indirect detection method is also realized by the direct detection meth...
